On Wednesdays we usually focus on general conditioning (fitness for life) and rarely on training for specific athletic endeavors. That's for a reason.
However, tough hiking is just an extreme variant of walking. A question might be "If you had three months to prep for a ten-day backpacking hike in Denali, or the Bob Marshall, or the White Mountains, or, like us, mountains in the Highlands, what would you do?"
I should modify that a bit. "What would you do, assuming you had a day job and little free time on weekends?"
I asked an exercise expert friend, a competitive athlete who can do several reps of 300-lb deads, that question. She said, given just an hour daily, the emphasis should be on lower body endurance and intense cardio. She said she would do two days/week of the usual powerlifts, but replace her other exercise routines with an hour of stairmaster with a 20-lb weight vest, and an hour of calisthenics with a 5-10-lb weight vest. She correctly observed that hill/mountain hiking is not mostly about strength but is about stamina, agility, and endurance. A person can be very strong without good endurance (and vice-versa). She said an hour of intervals on the bike would be fine, but an hour walking on treadmill with a 20-30 -lb weight vest at a high incline would be better for the purpose.
She also said that, from her experience, daily 7-hour mountain hiking with packs over 10 days can not really be duplicated in normal life. Best approach, when actually doing the trip, would be two to three days on, alternating with one lighter day for recovery. In fact, that is roughly what our guide had planned for our mixed group - two days hard, then one day lighter, and so on. By day 6, I felt eager to tackle anything. Pumped up and ready to go. Too soon, it was time to go home.
